Description.

Body length 6.7 –7.8/6.5– 7.6 mm, width 2.5-3.2 mm. Same coloured as Amphimenes bidoupensis but a little darker, with femora more strongly infuscate except at apices.

Eyes prominent to slightly reduced in size and a little flattened; posterior supraorbital seta situated slightly behind eye back margin. Antennae long, 3rd antennomere 1.58-1.70 times as long as 2nd, 8th 2.0-2.22 times as long as wide.

Pronotum 1.30-1.44 times as wide as long, 1.49-1.57 times as wide as head, weakly contracted basad, with side margin almost straight between antero- and posterolateral setigerous pores, hind angles subrectangular but rounded apically. Base medial part distinctly convex backwards, with a very shallow border, especially so at middle. Mid-line rather shallow throughout and shortly deeper where adjoining transverse basal depression; latter separated from disc convexity; lateral basal foveae weak. Paramedian foveae shallow but distinct.

Elytra same as in Amphimenes bidoupensis , 1.43-1.50 times as long as wide, and 1.51-1.55 times as wide as pronotum, with no depression between D2 and stria 6. D1/EL=0.22-0.25, D2/EL=0.65-0.75, D3/EL=0.91-0.95. Mesepisternum 1.38-1.42 times as long as wide.

Last tarsomere with two pairs of ventral setae. Male profemur without ventral tubercle.

Penis (Figs 20, 29, 38) similar to that of Amphimenes bidoupensis , but apical lamella longer, dorsolateral carina less developed basally, and endophallus of different structure.
